Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, and in particular to an ultrasonic magnetic resonance thermal physiotherapy head and physiotherapy instrument. Background Technology

[0002] Ultrasonic electromagnetic therapy is currently widely used in the treatment of soft tissue injuries and chronic pain, altering the physiological and biochemical processes of tissue cells to produce analgesic, anti-swelling, and blood circulation-promoting effects.

[0003] The prior art discloses an ultrasonic magnetic resonance thermal physiotherapy head and physiotherapy device (publication number: CN116963465A), which relates to the field of physiotherapy equipment technology, including a shell, an electro-physiotherapy device, an air-cooling device, an ultrasonic physiotherapy device, and a circulating cooling device.

[0004] In existing technologies, heat dissipation of the internal structure of the therapy head is achieved through physical changes between liquid and gaseous states. This requires the use of pipes to absorb heat from the inside of the shell. However, liquid liquefaction also occurs within the same pipe. While vaporization can absorb heat, liquefaction also releases heat, which limits the heat conduction effect of the pipes on the inside of the shell and reduces the heat dissipation effect. Furthermore, the circulation process of liquid-gas and liquid transformation within the pipes is relatively long, resulting in a slow response to temperature control.

[0005] Therefore, we propose an ultrasonic magnetic resonance thermal therapy head and therapy device. Utility Model Content

[0006] The present invention mainly addresses the technical problem of limited heat dissipation effect mentioned above, and provides an ultrasonic magnetic resonance thermal therapy head and therapy device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an ultrasonic magnetic resonance thermal therapy head and therapy device, comprising:

[0008] The shell and the top cover are snapped together. The shell has a cavity in which an ultrasonic head, an electromagnetic head and a heating coil are fixedly installed.

[0009] A heat dissipation assembly is installed on the top of the top cover to cool the cavity of the housing. The heat dissipation assembly includes a heat exchanger, a fan, and a circulation channel. The heat exchanger is fixedly connected to the top cover and extends into the cavity of the housing. A circulation channel for air circulation is opened on the top of the heat exchanger. The fan is fixedly installed at the port of the heat exchanger.

[0010] In a preferred embodiment of the present invention, the heat dissipation assembly further includes a pressure cap, an air inlet, and fins. The pressure cap is disposed above the top cover, and several air inlets are opened at the bottom of the pressure cap. Several fins are fixedly connected to the wall surface of the heat exchanger.

[0011] As a preferred embodiment of the present utility model, the bottom of the gland is provided with an integrally formed annular rib, and a plurality of air inlets are opened on the annular rib. The annular rib abuts against the top surface of the top cover, and a gap is left between the bottom surface of the air inlet and the top cover.

[0012] As a preferred embodiment of the present utility model, the heat exchanger forms a rectangular block structure, and the fins are metal plates with a rectangular cross-section in the horizontal plane. The fins are located in the cavity of the housing.

[0013] As a preferred embodiment of the present utility model, the circulation channel forms a U-shaped notch, the depth of the circulation channel is less than the thickness of the heat exchanger, and the fan is arranged at one of the ports of the circulation channel.

[0014] As a preferred embodiment of the present utility model, the heat dissipation component further includes a rib, the rib is fixedly connected to the top cover, the gland is fixedly connected to the top surface of the rib, the rib forms a rectangular rod structure, and the two sides of the circulation channel are symmetrically distributed with respect to the rib.

[0015] A physiotherapy instrument includes a physiotherapy instrument body, and the physiotherapy instrument body is provided with all the above-mentioned ultrasonic magneto-thermal physiotherapy heads.

[0016] The present utility model provides an ultrasonic magneto-thermal physiotherapy head and a physiotherapy instrument, which have the following beneficial effects:

[0017] 1. For the ultrasonic magneto-thermal physiotherapy head and the physiotherapy instrument, the fan sucks air into the circulation channel, and the air flows through the circulation channel and then discharges from the other port. The heat of the heat exchanger is taken away by the circulating air. Since a part of the heat exchanger is located in the cavity of the housing, the heat of the cavity of the housing is taken away by the metal heat exchanger, suppressing the heat accumulation and high temperature in the cavity of the housing, ensuring the working environment temperature of the electronic components, prolonging their service life, and ensuring the stability of the work. Secondly, the heat is taken away by the conduction of the heat exchanger. Since the circulation channel is not connected to the cavity of the housing, the air will not enter the cavity of the housing during heat exchange, reducing the interference of dust in the air to the electronic components.

[0018] 2. For the ultrasonic magneto-thermal physiotherapy head and the physiotherapy instrument, by setting the gland, the gland forms a shield on the top of the top cover.配合压盖的挡边,使得顶盖的顶部保持平整和美观,为了保障循环通道进气,通过各个进气口进气或者排气,空气从顶盖的顶部进入循环通道内再从循环通道另一开口排出,使得顶盖顶部的空气流动性大大加强,促进金属质地的顶盖带走热量,提高控温效果,进气口使得压盖的底部形成梳齿结构,抑制在进气过程中将大片杂质或者毛发吸入的现象,翅片能够增加换热体与壳体腔内空气的接触面积,进一步提高热量交换效率。

[0019] 3. This ultrasonic magnetic resonance thermal therapy head and therapy device, by setting ribs, uses the ribs to create a gap between the top cover and the top cover. Air enters the circulation channel from one side of the ribs and is discharged from the other side of the ribs through various air inlets, which improves the guiding effect of the air entering the gap and ensures smooth air intake and exhaust.

[0026] An ultrasonic magnetic resonance thermal therapy head and therapy device, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The housing 10 and the top cover 11 are snapped together. The housing 10 has a cavity, and an ultrasonic head, an electromagnetic head, and a heating coil are fixedly installed inside the cavity. A vibration motor is also fixedly installed inside the housing 10. The ultrasonic head is used to emit ultrasonic waves; the electromagnetic head is used to emit electromagnetic waves; the vibration motor is used to generate vibration; and the heating coil is a ring-shaped thermocouple used to generate heat. The electromagnetic head, ultrasonic head, vibration motor, and heating coil are connected to the controller of the physiotherapy device body via wires. The specific control method and usage method have been disclosed in detail in the prior art and will not be repeated here.

[0028] like Figure 2 , Figure 3 and Figure 5As shown, a heat dissipation component is provided on the top of the top cover 11 for cooling the chamber of the housing 10. The heat dissipation component includes a heat exchanger 30, a fan 32, and a circulation channel 31. The heat exchanger 30 is fixedly connected to the top cover 11 and extends into the chamber of the housing 10. A circulation channel 31 for air circulation is provided at the top of the heat exchanger 30. The fan 32 is fixedly installed at the port of the heat exchanger 30. The heat exchanger 30 forms a rectangular block structure. The fin 22 is a metal plate with a rectangular cross-section in the horizontal plane. The fin 22 is located in the chamber of the housing 10. The circulation channel 31 forms a U-shaped notch. The depth of the circulation channel 31 is less than the thickness of the heat exchanger 30. The fan 32 is provided at one of the ports of the circulation channel 31;

[0029] In this solution, the fan 32 sucks air into the circulation channel 31. The air flows through the circulation channel 31 and then discharges from the other port. The heat of the heat exchanger 30 is taken away by the circulating air. Since a part of the heat exchanger 30 is located in the chamber of the housing 10, the heat in the chamber of the housing 10 is taken away by the metal heat exchanger 30, inhibiting the heat accumulation and high temperature in the chamber of the housing 10, ensuring the working environment temperature of the electronic components, prolonging their service life, and ensuring the stability of the work. Secondly, the heat is taken away by the conduction of the heat exchanger 30. Since the circulation channel 31 is not connected to the chamber of the housing 10, air will not enter the chamber of the housing 10 during heat exchange, reducing the interference of dust in the air on the electronic components.

[0030] As Figure 3 and Figure 4 shown, the heat dissipation component further includes a gland 20, an air inlet 21, and fins 22. The gland 20 is provided above the top cover 11. A plurality of air inlets 21 are provided at the bottom of the gland 20. A plurality of fins 22 are fixedly connected to the wall surface of the heat exchanger 30. An integrally formed annular rib is provided at the bottom of the gland 20. A plurality of air inlets 21 are provided in the annular rib. The annular rib abuts against the top surface of the top cover 11. There is a gap between the bottom surface of the air inlet 21 and the top cover 11;

[0031] In this solution, as a supplement to the above solution, by providing the gland 20, a shield is formed on the top of the top cover 11 by the gland 20.配合压盖20的挡边,使得顶盖11的顶部保持平整和美观,为了保障循环通道31进气,通过各个进气口21进气或者排气,空气从顶盖11的顶部进入循环通道31内再从循环通道31另一开口排出,使得顶盖11顶部的空气流动性大大加强,促进金属质地的顶盖11带走热量,提高控温效果,进气口21使得压盖20的底部形成梳齿结构,抑制在进气过程中将大片杂质或者毛发吸入的现象,翅片22能够增加换热体30与壳体10腔内空气的接触面积,进一步提高热量交换效率。

[0032] As It should be noted that there is an unclear part in the description of item in the original text. I have tried my best to translate it according to the context, but it may need to be adjusted according to the actual situation. Figure 5 As shown, the heat dissipation assembly also includes a rib 33, which is fixedly connected to the top cover 11. The pressure cover 20 is fixedly connected to the top surface of the rib 33. The rib 33 forms a rectangular rod structure. The openings on both sides of the circulation channel 31 are symmetrically distributed with respect to the rib 33. By setting the rib 33, a gap is created between the pressure cover 20 and the top of the top cover 11. Air enters the circulation channel 31 from one side of the rib 33 and is discharged from the other side of the rib 33 through each air inlet 21, which improves the guiding effect of the air entering the gap and ensures smooth air intake and exhaust.

[0033] As not shown in the figure, a physiotherapy device includes a physiotherapy device body, a controller inside the physiotherapy device body, and an operation panel outside the physiotherapy device body. The controller is electrically connected to the operation panel. Electronic components inside the housing 10 are electrically connected to the controller via wires and plugs, which will not be described in detail here. The physiotherapy device body is equipped with all of the above-mentioned ultrasonic magnetic resonance heating physiotherapy heads. By setting the above-mentioned ultrasonic magnetic resonance heating physiotherapy heads, their lifespan is extended and their heat dissipation effect is good.

[0034] The working principle of this utility model is as follows: Air is drawn into the circulation channel 31 by the fan 32. The air flows through the circulation channel 31 and is then discharged from another port. The circulating air carries away the heat from the heat exchanger 30. Since part of the heat exchanger 30 is located inside the cavity of the shell 10, the heat inside the shell 10 is carried away by the metallic heat exchanger 30, thus suppressing heat accumulation and high temperature in the cavity of the shell 10. The pressure cap 20 forms a shield on the top of the top cover 11, and with the baffle of the pressure cap 20, the top of the top cover 11 remains flat and aesthetically pleasing. To ensure air intake in the circulation channel 31, air is introduced or exhausted through each air inlet 21. Air enters the circulation channel 31 from the top of the top cover 11 and then exits from another opening of the circulation channel 31, which greatly enhances the airflow at the top of the top cover 11 and promotes the removal of heat by the metal top cover 11. The ribs 33 create a gap between the pressure cover 20 and the top of the top cover 11, and air enters the circulation channel 31 from one side of the ribs 33 and then exits from the other side of the ribs 33 through each air inlet 21, improving the guiding effect of the air entering the gap.
